desired speed.

The hand control has a “double button” feature that allows you

to instantly speed up the motors without having to choose a

speed rate. To use this feature, simply press the arrow button

that corresponds to the direction that you want to move the

telescope. While holding that button down, press the opposite

directional button. This will increase the speed to the maximum

slew rate.

SeT up proCedureS

The LCM contains many user deﬁned setup functions designed

to give the user control over the telescope’s many advanced

features. All of the set up and utility features can be accessed

by pressing the MENU key and scrolling through the options:

Tracking Mode — Once the LCM is aligned, the tracking

motors will automatically turn on and begin tracking the sky.

However, the tracking can be turned off for terrestrial use:

Alt-Az: This is the default tracking rate and is used

when the telescope has been properly aligned.

EQ North: Used to track the sky when the telescope

is polar aligned using an equatorial wedge in the

Northern Hemisphere.

EQ South: Used to track the sky when the telescope

is polar aligned using an equatorial wedge in the

Southern Hemisphere.

Off:Whenusingthetelescopeforterrestrial(land)

observation the tracking can be turned off so that the

telescope never moves.

Note: EQ North and EQ South tracking modes are only

needed with telescopes that can be polar aligned. The

LCM series are exclusively Alt-Az mounted telescopes and

do not require equatorial tracking.

Tracking Rate — In addition to being able to move the

telescope with the hand control buttons, the LCM will

continually track a celestial object as it moves across the night

sky. The tracking rate can be changed depending on what type

of object is being observed:

Sidereal: This rate compensates for the rotation of

the earth by moving the telescope at the same rate as

the rotation of the earth, but in the opposite direction.

When tracking in Alt-Az mode, the telescope must

make corrections in both altitude and azimuth.

Lunar: Used for tracking the Moon when observing the

lunar landscape.

Solar: Used for tracking the Sun when solar observing

using a proper solar ﬁlter.

View Time-Site — View Time-Site will display the last saved

time and longitude/latitude entered in the hand control.

User Deﬁned Objects — The LCM can store up to 50 different

user deﬁned objects in its memory. The objects can be daytime

land objects or an interesting celestial object that you discover

that is not included in the regular database. There are several

ways to save an object to memory depending on what type of

object it is:

Save Sky Object: The LCM stores celestial objects

to its database by saving its right ascension and

declination in the sky. This way the same object can

be found each time the telescope is aligned. Once

a desired object is centered in the eyepiece, simply

scroll to the “Save Sky Obj” command and press

ENTER. The display will ask you to enter a number

between 1-25 to identify the object. Press ENTER

again to save this object to the database.

Save Database (Db) Object: This feature allows you

to create your own custom tour of database objects

by allowing you to record the current position of

the telescope and save the name of the object by

selecting it from any one of the database catalogs.

These objects then can be accessed by selecting GoTo

Sky Object.

Save Land Object: The LCM can also be used as

a spotting scope on terrestrial objects. Fixed land

objects can be stored by saving their altitude and

azimuth relative to the location of the telescope at the

time of observing. Since these objects are relative to

the location of the telescope, they are only valid for

that exact location. To save land objects, once again

center the desired object in the eyepiece. Scroll down

to the “Save Land Obj” command and press

ENTER. The display will ask you to enter a number

between 1-25 to identify the object. Press ENTER

again to save this object to the database.

Enter R.A. - Dec: You can also store a speciﬁc set

of coordinates for an object just by entering the R.A.

and declination for that object. Scroll to the “Enter

RA-DEC” command and press ENTER. The display

will then ask you to enter ﬁrst the R.A. and then the

declination of the desired object.

GoTo Object: To go to any of the user deﬁned objects

stored in the database, scroll down to either GoTo

Sky Obj or Goto Land Obj and enter the

number of the object you wish to select and press

ENTER. The hand control will automatically retrieve and

display the coordinates before slewing to the object.
